The refractory material refining quality steel casted by Henan province has reached top level of China

Currently, tourisms learn from Technology Department of Henan that the project of refractory material refining quality steel undertook by Luoyang Refractory Research Institute has passed acceptance check.. By carrying such an project, they have solved the key technology problem of short life span of LF+VD refining ladle refractory material that used in casting steel, and the life span increases from 85 heats to 135 heats. The person in charge of Technology Department of Henan has said that such a refractory material project has obtained two patents, formed productive capacity of 15 thousand ton per year and increased output value is 133 million. The appearing temperature of refractory material used by refining quality steel is lower 60℃～80℃ than ordinary ladle, which obviously reduces the power consumption of per ton steel, and very important for saving graphite and reduce heat loss of ladle. Now, with industrial structural adjustment of steel industry and increase of high quality special steel, which project carrying by Technology Department of Henan will promote such a proceeding in a big degree. If the factory in China can turn 5 million ordinary steel making to refining steel making per year, which will bring 12.5 billion income for steel industry, and the social benefits is obviously.
